SPECIFICATION forming part of Letters Patent No. 758,902, dated May 3, 1904, Application filed June l5, 1903. Serial N 161,536. (No model.)

To all whom it may concern,.-

Beit known that 1, FRANK DIoKINsoN, a citizen of the United States, residing at Springport, im the county of Jackson and State of Michigan, have invented new and useful .Improvements in Vaporizers for Explosive-Engines, of which the following' is a specification.

This invention is characterized particularly by an improved construction with' respect to the air-passages and the currents produced thereby which enter the mixing' orvaporizing chamber, and also by a g'auze pipe in which the gasolene flows through the vaporizingchamber. It is desirable that the flow of oil bc so controlled that it will not spatter or spill in the vaporizing-chamber or out of the airinlets thereto, because the feed is thereby varied or made uncertain. This is apt to occur in engines having an open flow of gasolene through the vaporizing-chamber, being caused by the jar of the engine or by the pitching of the engine in marine use. My invention avoids this defect by a continuous iiow of a stream of gasolene through a gauze tube in the mixingi chamber, which tube contines the stream therein, and yet permits the gas to be produced and taken up by the draft of air.

rEhe invention is illustrated in the accompanying drawings, in which-- Figure l is a side elevation of the vaporizer. Fig. 2 is a vertical cross-section thereof, and Fig'. 3 is a cross-section at right angles to Fig'. 2.

Referring' specifically to the drawings, the easing of the vaporizer is indicated at l, having therein a central cylindrical passage 9, which communicates at its upper end with a pipe l0, leading to the inlet-valve ofthe cylinder. Extending through the middle of this passage is a gauze pipe 5, through which the gasolene flows, and this pipe connects at the bottom of the casing with an overflow-pipe l1, leading back to gasolene-tank. This pipe 1l has an air-vent 12 to prevent back suction.

Opening' into opposite sides of the passage 9 are air-pipes T and 8 from the air-inlets 7 and S. The course of these air pipes or passages is down from the inlets, which are located in the side of the casing near the top whereof, to the bottom of the vaporizing-passage 9, through which the current flows upiwardly to the pipe under the suction of the engine-piston. The How of the current of air is thus contrary to that of the g'asolene, and

. the inflowing currents surround the gauze tube Ton all sides.

i At 2 is indicated the supply-pipe for the gasolene leading to a reservoir 3, which has an overflow 3, leading back to the tank. From the reservoir the gasolene flows through a passage 4, controlled by the needle-valve 6, to the top of the gauze tube.

The opposite location of the air-inlets into the vaporizing-passage cause-s the air-currents from the respective inlets to come in opposition at or near the bottom of the passage 9 and to focus into a whirling current, the axis of which is the gauze tube, which gives greater power to break up and vaporize the stream of gasolene. Also the gauze tube permits a continual How of g'asolene through the vaporizing-passage and contines the same, therebyT preventing it from spilling into the vaporizer, thus avoiding the objections heretofore indicated. The auxiliary reservoir 3 gives a supply of g'asolene at all times, irrespective of the stroke of the pump. rl`he flow of air is not merely across the stream of gasolene, but is along the same in an opposite direction, which is believed to be an important advantage with respect to vaporization. There is little or no tendency to blow the stream out of its course or to spatter it around ing an uncertain proportion of gas in the explosive mixture.

NVithin reasonable limits the gauze tube and the vaporizing-passage may be made of any length desired, according to local conditions.

WV hat I claim as new, and desire to secure by Letters Patent, is-

l. In a vaporizer, the combination with an air -passage, of a gauze oil-pipe extending' through the passage.

2. 1n a vaporizer, the combination with an air-passage, of an oil-pipe extending through where it is not wanted, thereby possibly creatthe passage and back to tank, permitting a continual circulation, and having a gauze section in the passage. l

3. In avaporizer, the combination with a perforated oil-pipe through which a stream of oil Hows in one direction, of a passage around the pipe, through which a current of air flows in opposite direction.

4. In a vaporizer, the combinationwith a perforated oil-pipe through which a stream of oil liows in one direction, of apassage around the pipe through which a vortex of air iows in opposite axial direction. l

5. In a vaporizer, the combination with a perforated oil-pipe through which a streannbf oil'ows, of a passage around the pipe having opposite air-inlets at one end andan outlet at the other end, producing a vortex of air through the passage around the pipe.

6. 1n a vaporizelgthe combination 'with a4 gauze oil-pipe through which a stream yof oil flows in one direction, of a passage around the pipe, having a plurality of air-inletsat one end and an outlet at the other end, through which passage a whirling current of air flows in opposite direction to the oil stream'.

7. In a vaporizer, in combination, a casing having a vertical passage therein, a vertical perforated oil -tube extending through the passage, through which tube the oil iiows downwardly, air-inlets in the casing opening into the lower end of the passage on opposite sides thereof, and a vapor-outlet from the top of the passage.

8. In a vaporizer, the combination with an oil-pipe having numerous fine perforations therein, and tank connections at each end, perinitting a continual circulation, of an air-passage around the pipe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK DICKINSON.
